Round Photo Corners

How It Works: 100% Browser-Based Corner Rounding

Our photo corner rounding tool runs entirely inside your web browser using HTML5 Canvas and client-side JavaScript. Unlike conventional image editors that force you to upload files to a remote server, our tool processes every pixel locally on your device.

This means zero upload delays, instant processing, and complete offline availability. Whether you are using a laptop, tablet, or smartphone, you can round any or all four corners of your images without wasting mobile data or waiting for cloud processing. Once the page is loaded, you can even disconnect your internet and continue editing seamlessly.

Why Privacy-First Image Editing Matters

Most free online photo tools silently send your personal images, profile pictures, and confidential graphics to external cloud servers. This creates unnecessary security risks, potential data leaks, and privacy concerns for sensitive photos.

We believe your images belong to you. By operating 100% offline and client-side, your photos are never uploaded, stored, or processed on any server. Your personal data never leaves your device's memory, making this the safest way to soften the edges of profile pictures, thumbnails, and app icons.

How to Round Your Photo's Corners (Step-by-Step)

Follow these simple steps to soften your image's edges:

1. Upload Your Image: Drag and drop your image into the workspace above, click to choose a photo from your computer or phone, or paste one from your clipboard with Ctrl/Cmd + V.
2. Choose Your Corners: Tap the circular dots sitting on the photo's four corners to switch each one on or off. Leave all four on for a fully rounded card, or turn off one or two for an asymmetric look.
3. Set the Radius: Drag the Corner Radius slider, or type a percentage, to control how rounded the selected corners are — anywhere from a gentle curve to a full pill or circle.
4. Download Your Image: Click Download Rounded Photo to instantly save your high-resolution, original-quality photo as PNG (transparent corners) or JPEG (corners filled with your chosen background colour).
5. Edit Many Photos at Once (Optional): Click Edit many photos at once (ZIP) to apply the same corner selection and radius to up to 100 images and download them together as a ZIP file.

Popular Uses for Rounded Photo Corners

Softening a photo's corners is a simple edit that instantly makes an image feel friendlier and more modern. Our tool is often used for:

• Profile Pictures & Avatars: Give a headshot or logo softened, app-icon-style corners.
• Website & App Thumbnails: Match rounded photo cards to a site or app's design language.
• Social Media Posts: Create a polished, on-trend look for carousel and grid images.
• Presentation & Print Graphics: Soften product or team photos before adding them to slides or documents.
• Stickers & Overlays: Round one or two corners only, for a peeled-sticker or tag effect.

About Remember Adjustments For Future Sessions

• Off by default: nothing is remembered unless you tick "Remember Adjustments For Future" under the Reset button.
• What it remembers: once ticked, your corner selection, radius, download size and JPEG background colour settings are reused the next time you add a photo or visit this page.
• Your privacy: these settings are saved in your own browser and never on our server.
• Easy to clear: untick the box at any time to erase the saved settings.

Frequently Asked Questions

Are my photos saved or stored on any server?

No. Your photos are never uploaded to any server. All corner rounding, radius adjustment, and rendering happen locally within your device's web browser.

Does this photo corner rounder work offline?

Yes! Once you open the web page, the app functions completely offline. You can turn off your Wi-Fi or mobile data and still edit and download images.

Can I round only some of the corners?

Yes. Tap any of the four dots on the photo's corners to switch that corner on or off. You can round anywhere from one corner up to all four.

Will the rounded corners be transparent?

Choose PNG in the Download menu to keep the rounded-off areas fully transparent. Choose JPEG instead if you need a smaller file — pick any background colour for those corners in JPEG Background Colour, since JPEG does not support transparency.

Will editing lower the quality of my image?

No. Our tool preserves your image's original resolution and exports clean, high-quality photos suitable for professional prints, social media, and personal projects.

How many images can I edit at once?

Up to 100 images in a single batch. Add your first photo, click Edit many photos at once (ZIP), pick a size, and choose the rest. The same corner selection and radius are applied to every photo, and they download together as one ZIP file. Because the work is done by your own device rather than a remote server, there is no daily limit, so you can simply run another batch.
